GSL1600X50 Compact 1600°C Tube Furnace with 50mm Alumina Tube, Vacuum Flanges, and Precise SCR Controller
The GSL1600X50 tube furnace is engineered for laboratory applications requiring high-temperature sintering of new material samples under vacuum or controlled gas atmospheres. Its compact design incorporates a 50 mm outer diameter alumina tube, enabling precise thermal processing within a 6-inch (152 mm) heating zone. This furnace is suitable for integration into glove boxes to facilitate experiments in various atmospheric conditions.
Temperature regulation is managed by a 30-segment programmable SCR digital controller, delivering ±1°C accuracy with PID control and auto-tuning capabilities. The heating elements consist of four Kanthal GLOBAR® silicon carbide rods rated for 1650°C, providing reliable and efficient heating up to a maximum of 1600°C for short durations and 1500°C for continuous operation.
Wichtigste Merkmale
- High-purity alumina tube (50 mm OD x 41.8 mm ID x 700 mm length) with excellent thermal stability.
- Vacuum flanges with KF-25 stainless steel valves and pressure gauge included for controlled atmosphere processing.
- Dual-layer shell with forced air cooling via two fans and 1800°C grade fibrous alumina insulation for energy efficiency.
- Programmable 30-segment SCR controller with PID and auto-tune, featuring over-temperature and thermocouple failure alarms.
- Heating elements are replaceable Kanthal SiC rods; installation is user-performed with video guidance provided.
- Compatible with optional temperature control software and Eurotherm 3004 controller for advanced data management and LabVIEW integration.
- Includes thermal couple (S-type) with alumina protective tube and ceramic tube blocks to minimize heat radiation.

Hinweise zur Konfiguration und zum Betrieb
The furnace includes alumina tube, vacuum flanges with valves and pressure gauge, thermal couple, ceramic tube blocks, and stainless steel tube covers. Heating elements are shipped separately to prevent damage and require user installation following provided video instructions. Optional accessories include temperature control software kits, Eurotherm 3004 controller, digital vacuum gauges, flow meters, and a mobile cart for ease of movement.
Users must ensure proper placement of ceramic tube blocks and calibrate temperature before use for accurate results. The furnace is designed for vacuum or low-pressure operation below 0.2 bar and vacuum pressures are safe up to 1500°C. Gas flow should be limited to less than 200 SCCM. Avoid heating under positive pressure with closed gas release valves to prevent damage. Graphite crucibles are not recommended for use inside the alumina tube.
